Prolactin Ovine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 199 amino acids and having a molecular mass of 23 kDa. The Prolactin n is purified by proprietary chromatographic techniques.
Additional Information
IntroductionProlactin is a neuroendocrine hormone synthesized primarily by the pituitary gland but also a variety of other cell types including the placenta, brain and uterus. Its primary function is to promote and maintain lactation but has also been shown to have a role in breast cancer development, regulation of reproductive function and immunoregulation.
SynonymsMammotropin, Luteotropic hormone, Luteotropin, PRL.
SourceEscherichia Coli.
Physical AppearanceSterile Filtered White lyophilized (freeze-dried) powder.
FormulationThe protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
SolubilityIt is recommended to reconstitute the lyophilized Prolactin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
StabilityLyophilized Prolactin althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Prl should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
